Say Y here if you want to be able to execute Linux/Intel ELF
binaries just like native Alpha binaries on your Alpha machine. For
this to work, you need to have the emulator /usr/bin/em86 in place.
You can get the same functionality by saying N here and saying Y to
"Kernel support for MISC binaries".
You may answer M to compile the emulation support as a module and
later load the module when you want to use a Linux/Intel binary. The
module will be called binfmt_em86. If unsure, say Y.
